Flutter has recently announced its major changes in the New Flutter 2.0 which was released at an event. The event was titled “Flutter Engage,” marking another milestone in the rapid development of the cross-platform UI toolkit and bringing along a lot of changes and announcements. This event was the summary of the “30 Days of Flutter” initiative, introducing Flutter to new audiences with the team and community coming together to achieve it.
What is the Major Changes in the New Flutter 2.0
Major Changes in the New Flutter 2.0–Null safety
Major Changes in the New Flutter 2.0 included Null safety has been the most important point for many developers trying to shift to Dart over languages like Kotlin. Null safety introduces types that cannot be null, allowing the compiler to know that some variables are not null and avoid unnecessary null checks.
At the same time, Major Changes in the New Flutter 2.0 also help developers avoid problems ahead of time because the code simply won’t compile if something isn’t handled properly. Null safety has been in testing for some time now and the entire framework has been shifted to work with null safety in a backward-compatible way.
One concern that people had ahead of time was how existing packages would work with null safety. Currently, major packages have already shifted or are planning to shift to null safety.
However, many remain in the non-null-safe versions. When an app uses a package that does not use null safety, the app runs in the unsound null safety mode — and sound null safety when all dependencies have been migrated to null safety.
Another Major Changes in the New Flutter 2.0 is Web reaches stable
Previously in the Flutter 1.0 launch event, Flutter has announced as Project Hummingbird. Flutter Web was something that caused quite a lot of excitement because Flutter could now reach the three major platforms: Android, iOS, and web. After a year and a half and multiple approaches to rendering, Flutter Web is finally stable after continuing to improve on performance. Flutter coming to the web had several obstacles at first: First, the widgets needed to be created to make an immersive, responsive web experience. Additionally, functionality such as hover needed to be implemented, enabling websites to not just look like a large mobile app. Finally, because Dart itself was originally meant as a replacement for JavaScript, the dart2js compiler was already widely used. However, the web itself is a tricky platform to deal with.
